All releases of GNU Zile

Release Notes: Actually uses libgc. All of the previous 2.4 releases were eating all your memory. Fixes the speed of searching on large buffers (previously, the entire buffer was copied for each search). The fix was copied from Zee. Makes query-replace and save file prompt handling closer to Emacs. Fixes many printf format bugs in user functions, thanks to GCC. Uses pkgconfig to find libgc. Improves the use of GCC warnings. Some code clean-up.

Release Notes: find-file and find-file-read-only now work non-interactively. Minor build system fixes have been applied. Some code cleanup has been done. A slight speed improvement has been made for general editing operations.
